The PIG (XR650L) is in need of some head work. It is evident by the fact that one of the seats for an exhaust valve has come lose and kinda wallered out the head. I was lucky I did not grenade the motor. Who does the best work? I am not looking for porting and such, just someone who can cut and install new seats and make sure the head is good to go. Thanks for your advise in advance.
